Cydia apps icons won't auto skin...they need to be made with frames....just look into this app and thi is how this app icon looks like...plain like that....changed without problems with Icons folder method

good to know, haven't given it very much thoughs tho, since it is the only icon on my iPhone that does not have any frame, I thought there has to be something wrong with it... just to figure out there's something wrong with me... sometimes I am just to lazy to dig deeper
